MILK-CAN.

SPECIFICATION forming part of Letters Patent No. 583,676, dated June 1, 1897.

I Application led July 31, 1896. Serial No. 601,277. (No model.)

T0 all ZIJ/"1,0m, it may concern:

Be it known that I, AVERY L. EMEEY, of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Milk-Cans, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. l Myinvention relates to an improved milkcan; and it consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

In the drawings, Figure 1 is a vertical sectional view of a can constructed in accordance with myinvention. Fig. 2 is an enlarged detailA vertical sectional View showing the faucet made use of in my improved milk-can. Fig. 3 is a vertical sectional view analogous to Fig. 2, showing the outlet-opening of said can closed while said can is being shipped or in storage. Fig. t is an enlarged sectional view of one of the escape-valves of which I make use in carrying out my invention. Fig. 5 is a side elevation of the cap used for closing the interior of the outlet-opening of my improved can.

Referring by numerals to the accompanying drawings, 1 indicates the outer cylinder of my improved milk-can, the same being constructed of any suitable sheet metal and provided with a bottom 2 and slightly-conical top 3. Fixed upon this top at points opposite one another are handles 4 of any common form.

5 indicates the inner cylinder of my improved can, the same being constructed of suitable sheet metal and of a diameter slightly less than the cylinder l. Said cylinder 5 is provided with a bottom 6 and top 7, there being the same space left between the tops and bottoms as there is space between said cylinders. The top 7 terminates in a tubular neck S, that extends upwardly through the top 3, and the upper end of said neck 8 is flared, as indicated by 9, and the extreme upper edge thereof is beaded and wired, as indicated by 10. The entire space between the inner and outer cylinders and the tops and bottoms thereof is packed with mineral wool or an 5o analogous non-conductor of heat and cold.

11 indicates a cylindrical receptacle that is of such size as that it will just pass through the neck 8, and the upper end of said receptacle is flared, as indicated by l2, in order that it will lit tightly upon the flared upper end 9 of said neck 8. vThe extreme upper end of said portion 12 is beaded and wired, as indicated by 13. Said cylindrical receptacle 11 is constructed with a bottom let, in the under side of which is formed a semicircular indentation 15, that lits directly over a hemispherical lug or body 16, that is fixed to the top surface of the bottom 6, at the centervthereof.

17 indicates a hollow plug or cap that is so constructed as that it will readily lit in the upper and ila-ring end of the cylindrical casing l1, and said-cap or plug is packed with mineral wool or analogous material and provided with ahandle 18,which facilitates the removal or placing in position of said cap or plug.

Y 19 19 indicate tubes `that are arranged on opposite sides of the center of the can and in -the top thereof, and the lower ends of said tubes extend within'the interior of said can and are there provided with perforated coverings 20. The upper ends of said tubes 19 extend outside the top 3, and in each of said protruding ends is formed an aperture 21. Directly opposite this aperture 21 in each of said tubes is formed apvertical slot 22, in which. operates a pin 23, that is fixed in the wall of a cap 24, the same being arranged to slide upon the protruding upper end of said tube. When these caps are at their lowermost limit of movement, the apertures 21 are entirely closed. Passing through the walls of the cylinders 1 and 5, adjacent the lower ends thereof, is a tube 25, on the inner end of which is a flange 26, that engages directly against the inner face of the inner cylinder 5, and the interior of said tube adjacent said flange is screw-threaded, as indicated by 27. Said tube projects a slight distance beyond the exterior of the outer cylinder l,.and the same is exteriorly screw-threaded.

28 indicates a faucet, the same being in the form of a straight tube having a llange 29 formed integral with its end, and the interior of the tube adjacent the flange 29 is screwthreaded in order that it may be located upon the protruding screw-threaded end of the tube 25. The faucet 28 is provided with a IOCl e essere spout 30 adjacent its outer end, and said outer end is exteriorly screw-threaded in order that it may receive a cap 31, on the inner face of which is formed a lug 32, through which passes a screw-threaded aperture 33. Formed integral with the inside of the tube comprising the faucet 2S,immediately in front of the spout 30, is a V-shaped flange or projection 34.

35 indicates a rod, the inner end of which is squared, as indicated by 3G, and upon the outer end of said rod is fixed an operatinghandle 37. A portion of said rod 35 adjacent said handle 37 is screw-threaded in order that said rod may be passed through the screwthreaded bore 33 in the cap 31 and lug 32. Upon said rod 35, at a point approximately the center thereof, is a disk 38, having an inclined face 39, that is arranged to engage Iagainst the front face of the V-shaped lug 34.

40 indicates a disk that is provided on its outer face with an ear 4l and upon its opposite face with an exteriorly-serew-threaded projection 42, which is of such size as that it will readily enter the in teriorly-screw-threaded end 27 of the tube 25. Formed in said screw-threaded projection 42 is a rectangular recess 43 of such size as that it will readily admit the squared end 36 of the rod 44 indicates an interiorly-screw-threaded cap that is constructed to be located upon the cxteriorly-screw-threadcd projecting end of the tube 25.

In the practical use of my improved milkcan if said can and contents are to be shipped the operator after thoroughly cleansing said can locates the screw-threaded portion of the cap 40 within the interiorly-screw-threaded end of the tube 27, and upon the projecting end of said tube 25 is located the cap 44. The receptacle 11 having previously been removed from the can to allow the operator to locate the plug 40 in the end oi' the tube 25 is now filled with ice, and after the can has been filled with milk said ice can or receptacle 1l is placed in positionin the milk-can, or until the fiared portion 12 of said receptacle rests directly upon the flared portion 9 of the neck of the can. To allow the escape of gases, &c., arising from the Volume of milk within the can, the operator raises the caps 24 on the ends of the tubes 19 until the apertures 2l are exposed. The pins 23, engaging in the slots 22, prevent the caps 24 from being accidentally removed or lost from the ends of the tubes 19.

When it is desired to locate the faucet on the can, the operator removes the cap 44 from the protruding end of the tube 25, and after manipulating the handle 37, so that the disk 3S on the rod 35 bears against the flange 34, passes the squared end of said rod 35 through the tube 25 and into the squared recess 43 in the cap or plug 40. In this position the eX- teriorly-screw-threaded end of the faucet 23 is ready to enga-ge upon the screw-threaded projecting end of the tube 25. As said faucet is screwed onto said projecting portion of the tube 25 the squared end 3G of the rod 35, engaging in the recess 43, will cause the cap 40 to be unscrewed from the inner end of said tube 25. Consequently when the faucet has been firmly seated upon the protruding end of the tube 25 the cap 40 will be entirely unscrewed from theropposite end of said tube. By now manipulating the handle 37, so that the disk 33 on the rod 35 moves away from the flange 34, the milk from the interior of the can will pass through the tube 25 into the faucet and freely flow from the spout thereof. Vhen the can is empty and it is desired to reship the same, the operator removes the faucet and relooates the cap 44 on the protruding end of thetube 25. This leaves the cap 40 within the can, from whence it may be removed before again cleansing and refilling the can.

A milkcan constructed in accordance with the foregoing description is very efficient in use, can be easily cleaned, is capable of being provided with a fresh supply of ice as often as desired, and as the faucet for said can is removable said can may be stored in less space and handled much easier than if said faucet were permanently fixed to said can.
